The rice stem bug, Tibraca limbativentris Stal, is an important pest of rice in Brazil. This work evaluated the occurrence of parasitoids in eggs of T.limbativentris egg parasitism in rice crops in the Maranhão State. The eggs collected exhibited an average parasitism of 32%. The parasitoids collected were Telenomus podisi (Ashmead), Trissolcus urichi (Crawford) (Hymenoptera: Scelionidae) and Oencyrtus submetallicus (Howard) (Hymenoptera: Encyrtidae).
稻茎蝽（Tibraca limbativentris Stal）是巴西水稻的一种重要害虫。本研究评估了马拉尼昂州稻田中稻茎蝽卵的寄生蜂发生情况。所收集的卵平均寄生率为32%。收集到的寄生蜂有豆荚卵蜂（Telenomus podisi (Ashmead)）、乌氏螯蜂（Trissolcus urichi (Crawford)）（膜翅目：缘腹细蜂科）和亚金属恩蚜小蜂（Oencyrtus submetallicus (Howard)）（膜翅目：跳小蜂科）。
